Specification of Letters Patent.

Patented May 29, 1906.

Application filed August 2, 1905- Serial No. 272,385.

To all whom it may concern.-

Be it known that I, PRESTON K. ALBRIGHT, a citizen of the United States, residing at Binghamton, New York, have invented certain new and useful Im rovements in Knockdown Sleds, of which t e following is a specification. I

My present invention relates to improvements in knockdown sleds; and the object of the lnvention is to provide a sled which may be folded into compact space for shipping and storing, but which when unfolded or set u will have all the attributes of strength, rigidity, durability, and lightness of the ordinary sled.

The invention is illustrated in the accompanying drawings, in which-- Figure 1 is a side elevation, and Fig. 2 a cross-section. Fig. 2 is a view folded.

In the drawings the runners are shown at 3 and may be made of any suitable material, preferably of metal. They are preferably curved upward and backward, as shown at 3 and may very desirably be continued rearwardly as an inte ral piece to form the side bars 4. Attache to and rising from corresppnding points upon each runner are two t 'n flat bars 5, of steel or other desirable metal, that converge to about their midlen th and then run parallel to each other Wit a narrow space between. A bracket 6 has a vertically-disposed Web 6*, located between the arallel parts of the bars 5 and secured in p ace by a rivet 7. Each bracket also has a horizontally-extending ear or lug 6 to which the side bar 4 is bolted. The numerals 7 7 indicate cross-bars, likewise of metal, to which the board 8 is secured by metal clips 9, which have vertical portions 9 riveted to the cross-bars and turned-over ends 9 engaging the edges of the board. Each end of each cross-bar is desi ned to rest between and be embraced by t e ends of the parallel portions of the bars 5, and the web 6 is located in the pro er position to form a stop for the end of tile cross-bar to rest upon. Likewise the vertical portions 9 of the clips 9 are situated so as to act as stops against which the upper ends of the bars or members 5 rest. Additional means, however, may be provided for detachably connecting the overlapping ends of the bars 5 and 7, such as bolts 10, passing through alming openings. Inclined braces 11 have their outer ends pivotally connected to and between the bars 5 at or near the point where they diver e. The inner ends of these braces are pivotaIly connected to opposite sides of the cross-bars 7 It will thus be seen that when the upper ends of the bars 5 are disconnected from the ends of the cross-bars they may be swung on their pivots and the whole sled folded into the compact position shown in Fig. 2*.

Having thus described my invention, what I claim is 1. A knockdown sled comprising cross-bars and runners, standards rising from the runners and having their upper ends detachably connected to the outer ends of the cross-bars, and inclined braces having their opposite ends pivotally connected to the standards and cross-bars, substantially as described.

2. A knockdown sled comprising a pair of runners each curving upward at the front and backward to form an integral parallel side rail, standards rising from the runners and secured to the side rails, cross-bars having their ends detachably connected to the upper ends of the standards, and inclined braces having theirends pivotally connected to the standards and cross-bars, substantially as described.

3. A knockdown sled comprising a pair of runners and side rails, two-part standards rising from the runners, a bracket clamped between the two parts of each standard and connected to the rail, cross-bars having their ends resting between the standards and on said brackets, braces pivotally connecting the cross-bars and standards, a seat-board, and clips clamping said board to the crossbars and serving as stops against which the up er ends of the standards abut, substantia ly as described.

In testimony whereof I afliX my signature in presence of two witnesses.

PRESTON K. ALBRIGHT.
